To all fwwm it may concern Be it known that Rie/Ianni) i). BUReinLL, e citizen of he United States, i'esiding elm Tampa, in the county of Hiilsborough and n Vtete of Floiidn, have 'invented n new and useful Motor-Sleigh, of which the lf'oiiovving is a specification.

The device forming he subject ineei' of his nppiiceion is e niotoisleigh, and one object of the invention is to provide ncvei actuatingmeinbeis, which, conci-ing with 'the ice-covered or snow-covered gi'ound7 impart movement te the sleigh.

A fui-ther object of the invention is io piovide novel ineens for driving,` the actuating members; y v

The invention contemplates novel ineens. whereby the actuating members may be een pied up operatively with in engine.

It is Within die province of the disciosuie to improve generaiiy and to enhance the yutiiitv of devices of that type io which the present invention eppei'eins.

iViti the above and .othei objects in view which will apgeai as the desci'ipeion proseeds, 'ne invention resides in the combine,- tion and arrangement oi pei-is, and in the details of construction hereinafter described and eieimed, it being undersood 'time changes in the psfeeise einioodiinenLl of die in- Veni-ion herein disclosed can be mede Within he scope of what is claimed Witiien depainting from tilespirii, of the invenion.

Ball and socket joints29 connect one end of the link' 24 with thepost and connect the other end of the link 24 with the crank arm 28.

`Wlen the shaft 26 is rotated by means of the wheel 27, the crank. arm 28 through the- 1n which is'journaled for rotation a shaft-33 having cranks 35, A sprocket wheel 36 is 37 is 'secured'to the shaft 31.

v'lhe numeral 38 denotesy the leasing of 4a suitable transmission mechanism of any sort, fixed to the turntable l5, the platformlhaving an arcuate opening 39 in which the transmission mechanism moves when. the

turntable l5 is rotated darin@ the steerin i e operation.

The numeral 40 designates a shaft con-l stituting apart of the transmission mechanisin andA located below the turntable l5.'

Mounted on the shaft 40 are sprocket wheels ,4L-.Chains 42 connect the sprocket wheels 4l, respectively, with the sprocket wheels 36 and l3?- of the shafts 33 and 3l. At 43 there appears the shaft of an internal combustion engine 44, the shaft 43 4being ,opeazutively connected with the transmissiony mechanism, and the engine 44 being mounted on the lturntable 15. .The platform l is provided with 'an arcuate opening 45 through which the engine 44 projects, the construction being such that when the turntable l5 is moved during the steering operation, the engine 44 which is lixed to the turntable, may move with respect to the platform 1.

A plurality of groundengaging means are provided, wherebyl movement may be imparted to the sleigh.` But one of these grow1nd-engagiiipr mechanisms need be described, although four of them are provided,

the ground engaging mechanisms being operatively connected with'the cranks 34 and 35 of the shafts 3l and llhe description will be A.conlined to one of the cranks (Llpcratrcly connected with the crank 35 is a casing 46 within which i's"located a plunger 4T, lthe forward end oftheicasing 46 being,T recessed :xs-shown at48 to receivel the forucird end of the plunger. Surroundi ing a. portion of the plunger 47 and locatedin the casing 46 is a spring 49 the forward end yof which abuts against the forward end- 1,2 idees of the casing, the-rear end of which is engaged with an abutment on the plunger 47,

the ab lit-ment being in the form of a cross pin 5() .if desired. The rear, lower end of the plunger 47 1s pivoted as shown at 5l to an arcuate shoe 52 provided lw1th depending teeth 53, the rear end of the slice beingis in operation, the shaft-43 is rotated and, motion. is, imparted through the transmis- Y sion mechanism 38 to the shaft 40. The sprocket wheels 41 are rotated andby means of the chains 42 and the sprocket wheels 36 and 37,"rotation is imparted to the shafts 33 and 3l, the cranks 35 and 34'0f which:

'are thus` operated. A reciprocating swingserving to take up excessive jars. The shoes 52 are worked to and fro, the links 55 the showing of the forward and rear shoes 52 in Fig. l of the drawings, it will be obvious that the shoes are lifted as they are moved forwardly, and that the shoes de- *.ingmovenient is imparted to the plunger's 47 i by 'way of the casings 46, the springs 49' swinging on the .pivot elements 56.' Noting scend as they move rearwardly. The con# struction, therefore, is such that the sleigh underthe impulse of the shoes 52 will be given a forward movement, the teeth 53 giving the'y shoes a hold on the ice covered ground, as the shoes 52 move rearwardly.

The engine 44, the transmission mech.

anism 38 and 'attendant parts may l, be,
